Abstract

The authors report the observation of exchange bias in bulk polycrystalline Ni₅₀Mn_25+xSb_25−x Heusler alloys. Shifts in hysteresis loops of up to 248 Oe were observed in the 5 T field cooled samples. The observed exchange bias behavior in Ni₅₀Mn_25+xSb_25−x is attributed to the coexistence of antiferromagnetic and ferromagnetic exchange interactions in the system. Such behavior is an addition to the multifunctional properties of the Ni₅₀Mn_25+xSb_25−x Heusler alloy system.
